Chemo-orientation responses in hymenopteran parasitoids induced by substrate-borne semiochemicals

2013

Hymenopteran parasitoids can utilize substrate-borne semiochemicals released by conspecifics or by their hosts, increasing the likelihood of successful mating and host location. According to the literature, two substrate-borne chemo-orientation patterns can occur: (1) biased random searching, a non-directional reaction toward the chemicals (kinesis), and (2) trailfollowing searching, a directional response toward the source emitting the chemical compounds (taxis). These two different strategies can be adopted by parasitoids to locate hosts and mates. In host location, random searching is induced by allelochemicals indirectly associated with the host, whereas trail-following behavior is indu…

Meta-Analysis in Epidemiology

2007

The use of meta-analyses in order to synthesise the evidence from epidemiological studies has become more and more popular recently. It has been estimated by Egger et al. (1998) that from articles retrieved by MEDLINE with the medical subject heading (MeSH) term “meta-analysis” some 33% reported results of a meta-analysis from randomised clinical trials and nearly the same proportion (27%) were from observational studies, including 12% papers in which the aetiology of a disease was investigated. The remaining papers include methodological publications or review articles. Reasons for the popularity of meta-analyses are the growing information in the scientific literature and the need of time…

When saying that you are biased means that you are acurate? The moderating effect of cognitive structuring on relationship between metacognitive self…

2019

The aim of our study was to answer two questions: 1. How accurate are the reports of people who assert they are biased? 2. Why do people who know they are biased tend to engage in more inappropriate behavior? A total of 340 under- graduate students participated in the study. They followed a special procedure measuring cognitive structuring, efficacy to fulfill personal need to achieve cognitive structuring, metacognitive self (i.e. self-awareness of biases), and the level of performed confirmation bias. The procedure was created for investigating confirmation bias concerning the perception of self versus others. The first question may be answered by the assertion that the more metacognitive…

Ptiliolum marginatum (Aube, 1850) (Coleoptera: Ptiliidae)– gatunek nowy dla Polski z Białowieskiego Parku Narodowego

2021

We present the first record of Ptiliolum marginatum for Poland. The specimens have been extracted from two nests of the wood warbler Phylloscopus sibilatrix in 2020, during investigations of the invertebrate fauna inhabiting bird nests. The samples were collected in the strictly protected part of the Białowieża National Park, in eastern Poland. We provide general information on the geographical distribution of Ptiliolum marginatum in Europe, the state of knowledge of the genus Ptiliolum in Poland, and further documentation including colour photographs of dorsal and ventral habitus, and characteristic features of hind femora and spermatheca of females.

Neoemozioni e colletti bianchi. Uno studio qualitativo

2013

L’organizzazione criminale Cosa Nostra, nell’ultimo decennio, ha avviato un processo di profonda trasformazione organizzativa e culturale. Gli inevitabili ricambi generazionali, così come il processo di finanziarizzazione e internazionalizzazione della mafia, hanno comportato un progressivo abbandono del modello rigidamente centralista in favore di strutture reticolari collegate tra di loro e ricche di relazioni esterne. I colletti bianchi, punti nodali della rete criminale, svolgono un importante ruolo di cerniera tra l’organizzazione criminale, la politica, l’economia. Obiettivo dello studio è comprendere quali modalità relazionali sostengono il sistema di potere mafioso-clientelare e ind…

Default effects in app selection: German adolescents’ tendency to adhere to privacy or social relatedness features in smartphone apps

2019

Cognitive biases such as default effects impact on user preferences for a broad range of different choices. This paper investigates these default effects among adolescents configuring apps that either satisfy relatedness or enhance autonomy by protecting privacy. Relatedness and privacy are two innate needs that adolescents can satisfy with the use of smartphone apps. This study argues that adolescents’ choice of features supporting either privacy protection or social relatedness is a consequence of default effects, so that adolescents adhere to preselected defaults. We test this assumption in an experimental survey design including four app configuration tasks with N = 280 German adolesce…

Memory limited inductive inference machines

1992

The traditional model of learning in the limit is restricted so as to allow the learning machines only a fixed, finite amount of memory to store input and other data. A class of recursive functions is presented that cannot be learned deterministically by any such machine, but can be learned by a memory limited probabilistic leaning machine with probability 1.

Bias artifact suppression on MR volumes.

2007

RF-Inhomogeneity correction is a relevant research topic in the field of Magnetic Resonance Imaging (MRI). A volume corrupted by this artifact exhibits nonuni- form illumination both inside a single slice and between adjacent ones. In this work a bias correction technique is presented, which suppresses this artifact on MR vol- umes scanned from different body parts without any a-priori hypothesis on the artifact model. Theoretical foundations of the method are reported together with experimental results and a comparison is presented with both the 2D version of the algorithm and other techniques that are widely used in MRI literature.

Multiferroic BiFeO<inf>3</inf> for conductance control at the LaAlO<inf>3</inf>/SrTiO<inf>3</inf>-interface

2015

Multiferroic materials possessing both magnetic and ferroelectric order enable in principle to switch order parameters using not the direct reciprocal field, e.g. to switch the magnetization by an electric field or the electric polarization by a magnetic field. A recent breakthrough was achieved by the demonstration of the ferromagnetic switching of a Co layer with an electric field employing the multiferroic BiFeO 3 [1]. The latter material is a perovskite based oxide that shows stable ferro-electricity as well as an antiferromagnetic order at room temperature [2,3]. Due to a Dzyaloshinskii-Moriya interaction induced by rotation of oxygen octahedra leading to noncollinear Fe-O-Fe bonds a s…
